Automotive buck regulator and controller with voltage monitors and watchdog timer

A frequency watchdog monitors the external clock at the SYNCIN pin. If the external clock is not present or

invalid, the device automatically switches to the internal clock. The device switches back to the external clock if

the frequency watchdog detects a valid input.

When the external clock is selected, the switching regulators should be set in PWM mode at the application

level to ensure clock synchronization.

14.6 SYNCOUT function settings

The GPIO2 pin may be configured as SYNCOUT via OTP by setting OTP_GPIO2_CFG[1:0] = 0b10. When

configured as SYNCOUT, GPIO2 outputs the clock that the SW1 regulator uses (in terms of phasing and

frequency) in a push-pull mode railing to VDDIO and ground.
